    <p>I have a <code>searchDisplayController</code> which works perfectly when searching for English and Arabic words using a method as follows:</p> <pre><code>- (void)filterContentForSearchText:(NSString*)searchText scope:(NSInteger)scope { NSString *query = self.searchDisplayController.searchBar.text; if (query &amp;&amp; query.length) { NSPredicate *predicate = [NSPredicate predicateWithFormat:@"ClientName contains[cd] %@", query]; [searchResultController_.fetchRequest setPredicate:predicate]; } NSError *error = nil; if (![[self searchResultController] performFetch:&amp;error]) { // Handle error NSLog(@"Unresolved error %@, %@", error, [error userInfo]); exit(-1); // Fail } } </code></pre> <p>However, this works fine if the iphone language is English, but if I change the iPhone language to Arabic (global settings) and tried to search in Arabic or English words the <code>searchResultsController</code> will not display results, why ?</p> <p>p.s. when I put a static Arabic word in query like this: <code>NSPredicate *predicate = [NSPredicate predicateWithFormat:@"ClientName contains[cd] %@", @"تجريب"];</code> the <code>searchDisplayController</code> will display the correct result of the arabic word <code>تجريب</code></p> <p>EDIT: I've tried to build the predicate in code like this :</p> <pre><code> NSExpression *clientNameEx=[NSExpression expressionForKeyPath:@"ClientName"]; NSExpression *aClientEx=[NSExpression expressionForConstantValue:query]; NSPredicate *predicate=[NSComparisonPredicate predicateWithLeftExpression:clientNameEx rightExpression:aClientEx modifier:NSDirectPredicateModifier type:NSContainsPredicateOperatorType options:0]; </code></pre> <p>but to no avail ...</p>

    1. COUse searchText instead of the text in searchBar. And please, NSLog() the received string in searchText and compare with the literal string that works fine as you say in your p.s. So we will know if the problem is with that string.

    2. COI have done this, the NSLog shows the same literal arabic string in the p.s. section of my question, BUT what drives me crazy is that the result is empty !!

    3. COAnd what if you compare both strings with ´[@"تجريب" compare:searchText]´ ? What does it return? NSOrderSame?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
